Given below are four statements pertaining to the separation of DNA fragments using gel electrophoresis. Identify the incorrect statements:
| (a) | DNA is a negatively charged molecule and so it is loaded on gel towards the anode terminal. |
| (b) | DNA fragments travel along the surface of the gel, whose concentration does not affect the movement of DNA. |
| (c) | The smaller the DNA fragment, the greater the distance it travels through it. |
| (d) | Pure DNA can be visualized directly by exposing it to UV radiation. |
Choose the correct answer from the options given below:
| 1. | (a), (c) and (d) | 2. | (a), (b) and (c) |
| 3. | (b), (c) and (d) | 4. | (a), (b) and (d) |
